[0043] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the present invention is an arm exercise device for athletes, the retracting assembly 10 includes a reeling roller 1001 fixedly mounted on a transmission rod 901, a retracting rope 1002 connected to a tension plate 705 is wound around the reeling roller 1001, and a guide wheel 1003 adapted to the retracting rope 1002 is mounted on a bearing on the rotating frame 302.

[0044] Working principle: The device is installed in the exercise area. Before the athlete needs to exercise his arms, the device is converted from a horizontal state to a vertical state, and the driving motor 401 is started. The output shaft of the driving motor 401 rotates to drive the active bevel gear 402 to rotate, and the active bevel gear 402 rotates to drive the driven bevel gear 403 to rotate. The driven bevel gear 403 rotates to drive the rotating rod 301 to rotate, and the rotating rod 301 rotates to drive the rotating frame 302 to rotate. At the same time, the winch 501 is used to reel in the output rope 503. Under the guidance of the guide wheel 1 504, the output rope 503 drives the connecting ring 502 to pull the rotating frame 302 until the rotating frame 302 rotates to a vertical state. The rotating frame 302 drives the supporting assembly 6, the weighting assembly 7, the exhaust assembly 8, the transmission assembly 9 and the retractable assembly 10 to rotate to a vertical state.

[0045] When exercising the arms, the athlete enters between the rotating frame 302 and the support frame 1 and activates the hydraulic push rod 3042. The output end of the hydraulic push rod 3042 drives the support inner plate 3043 to move inside the support outer plate 3041 until the support inner plate 3043 contacts the ground, forming a vertical support effect for the rotating frame 302.

[0046] Start the air pump 801, and under the action of the air extraction pipe 802, the gas in the weighted cylinder 702 is extracted to a reasonable level, so that the gas in the weighted cylinder 702 is in a negative pressure state, thereby adjusting the sliding difficulty of the piston 703 in the weighted cylinder 702, forcing the force to adapt to the athlete's arm pulling force, the athlete's arm pushes the bracelet 11, and the bracelet 11 drives the transmission spur rack 903 to move, so that the transmission spur rack 903 drives the sliding rod 601 to move, so that the block 602 drives the sliding spring 603 to move, and at the same time the transmission spur rack 903 drives the transmission gear 902 to rotate, and the transmission gear 902 drives the transmission The rod 901 rotates, and the transmission rod 901 drives the winding roller 1001 to move, forcing the winding roller 1001 to tighten the take-up rope 1002. Under the guidance of the second guide wheel 1003, the take-up rope 1002 is forced to drive the tension plate 705 to move, so that the tension plate 705 pulls the weighted rod 704, so that the weighted rod 704 drives the piston 703 to move in the weighted cylinder 702. At the same time, the weighted spring 706 is stretched. Since the gas in the weighted cylinder 702 is partially extracted, the athlete needs to push or pull the bracelet 11 hard, so that the arm feels the force. Pushing and pulling the bracelet 11 back and forth exercises the athlete's arm.

[0047] Before exercising the legs, the device is converted from a vertical state to a horizontal state, and the drive motor 401 is started in the reverse direction. The output shaft of the drive motor 401 rotates, driving the active bevel gear 402 to rotate in the reverse direction. The active bevel gear 402 rotates, driving the driven bevel gear 403 to rotate in the reverse direction. The driven bevel gear 403 rotates, driving the rotating rod 301 to rotate in the reverse direction. The rotating rod 301 rotates, driving the rotating frame 302 to rotate in the reverse direction. At the same time, the output rope 503 is wound up by the winch 501. Under the guidance of the guide wheel 1 504, the output rope 503 drives the connecting ring 502 to pull the rotating frame 302 until the rotating frame 302 rotates to a horizontal state. The rotating frame 302 drives the supporting assembly 6, the weighting assembly 7, the exhaust assembly 8, the transmission assembly 9, and the retractable assembly 10 to rotate to a horizontal state.

[0048] When exercising the legs, the hydraulic push rod 3042 is activated, and the output end of the hydraulic push rod 3042 drives the support inner plate 3043 to move inside the support outer plate 3041 until the support inner plate 3043 contacts the backrest plate 2, so that the support inner plate 3043 and the backrest plate 2 form a supporting effect for the athlete. At this time, the support block 305 just contacts the ground, forming a horizontal supporting effect for the rotating frame 302;

[0049] Since the legs are longer than the arms, the position of the foot pedal 12 needs to be adjusted. At this time, the connecting valve 803 is opened, forcing the weighted cylinder 702 to be connected to the atmosphere, so that the air pressure in the weighted cylinder 702 is equal to the atmospheric pressure, pushing the transmission spur rack 903, the transmission spur rack 903 drives the transmission gear 902 to rotate, the transmission gear 902 drives the transmission rod 901 to rotate, and the transmission rod 901 drives the winding roller 1001 to move, forcing the winding roller 1001 to drive the retracting rope 1002 to tighten, under the guide action of the guide wheel 1003. The tension plate 705 is driven by the tension rope 1002, which pulls the weighted rod 704, and the weighted rod 704 drives the piston 703 to move in the weighted cylinder 702. At the same time, the weighted spring 706 is stretched to a reasonable degree until the distance between the footboard 12 and the backrest board 2 is adapted to the length of the leg. At this time, the connecting valve 803 is closed, and the athlete enters the space between the rotating frame 302 and the support frame 1, lies down, leans against the backrest board 2, and places the legs on the support inner plate 3043, with the feet in contact with the footboard 12.

[0050] Start the air pump 801, and under the action of the air extraction pipe 802, the gas in the weighted cylinder 702 is extracted to a reasonable level, so that the gas in the weighted cylinder 702 is in a negative pressure state, thereby adjusting the sliding difficulty of the piston 703 in the weighted cylinder 702, forcing the force to adapt to the push and pull force of the athlete's legs. The athlete's legs push the foot pedal 12, and the foot pedal 12 drives the transmission spur rack 903 to move, so that the transmission spur rack 903 drives the sliding rod 601 to move, so that the block 602 drives the sliding spring 603 to move, and at the same time the transmission spur rack 903 drives the transmission gear 902 to rotate, and the transmission gear 902 drives The driving transmission rod 901 rotates, and the transmission rod 901 drives the winding roller 1001 to move, forcing the winding roller 1001 to drive the take-up rope 1002 to tighten. Under the guidance of the second guide wheel 1003, the take-up rope 1002 is forced to drive the tension plate 705 to move, so that the tension plate 705 pulls the weighting rod 704, so that the weighting rod 704 drives the piston 703 to move in the weighting cylinder 702, and at the same time the weighting spring 706 is stretched. Since part of the gas in the weighting cylinder 702 is evacuated, the athlete needs to push the foot pedal 12 hard, so that the legs feel the force, and the athlete's legs are exercised by pushing and pulling the foot pedal 12 back and forth;

[0051] On the one hand, this solution can switch the exercise mode, allowing athletes to switch between exercising their arms and legs, which is beneficial to the comprehensive exercise of the athletes' arms and legs, thereby forming an integrated device, reducing equipment costs, occupying less space, and improving the versatility of the device; on the other hand, during the switching process, the position of the hand band 11 and the foot pedal 12 can be adjusted, so that the device can adapt to the arms and legs, improving the control and adjustment capabilities of the device, and improving the comfort of athletes when exercising their arms and legs.
